Abstract: A sulfonated (SO3H-bearing) Carbon-based solid acid catalyst was prepared from pine wood powder — a cheap forest waste. The catalyst was obtained by the carbonization, activation and sulfonation of pine wood powder. The specific surface area and SO3H density of the carbon catalyst were 1364 m2/g and 1.36 mmol/g, respectively. The catalytic activity of carbon catalyst was investigated on the acetic acid esterification reaction and compared with that of several commercial solid acid catalysts, such as Amberlyst-15, Nafion NR50 and Nafion SAC-13. The results showed that the catalytic activity of carbon catalyst was lower than that of Amberlyst-15, but higher than that of Nafion NR50 and Nafion SAC-13. Its cost is much lower than that of Nafion NR50 and Nafion SAC-13. It also showed that carbon-based solid acid catalyst can be prepared by carbonization, activation and sulfonation of pine wood powder.

Key words: pine wood powder, high specific surface area, carbon-based solid acid, catalyst
